Description

Technical Field

[0001] This invention relates to the field of pipe cutting technology, and in particular to a pipe cutting device for power construction. Background Technology

[0002] In the process of power construction, power conduits are an indispensable key material. Power conduits are mainly used to protect power cables, preventing them from being damaged by external mechanical forces and environmental corrosion during construction and subsequent use. At the same time, they also provide a stable laying channel for cables, ensuring the orderly arrangement and smooth laying of cables, avoiding cable tangling and compression, and ensuring the reliability and safety of power transmission. In actual construction, power conduits often need to be cut according to the specific construction site conditions and cable laying path. Cutting the power conduits allows their length to be adapted to the cable laying distance of the construction site, avoiding material waste. Furthermore, the cut power conduits can be better connected and combined with other power construction auxiliary facilities.

[0003] During the cutting and processing of power pipes, when the power pipe is long, it usually needs to be fixed on a workbench of matching length for operation. After cutting a section of power pipe, in order to continue cutting the remaining part, the position of the power pipe on the workbench needs to be adjusted and it needs to be fixed again using the clamps on the workbench. However, when cutting long power pipes, a lot of waste chips often adhere to the surface of the workbench. If these waste chips are not cleaned in time, they will gradually accumulate on the workbench. When a new power pipe is placed for cutting, the surface of the power pipe will come into contact with the waste chips on the workbench, which may hinder the cutting operation and affect the cutting efficiency.

[0004] To address the aforementioned problems, this application proposes a pipe cutting device for power construction. Summary of the Invention

[0005] This invention proposes a pipe cutting device for power construction, which solves the problems in related technologies where long power pipes need to be fixed on a workbench for segmented cutting, and the position needs to be adjusted and re-fixed after each cutting. In addition, the workbench is prone to accumulating waste chips during power pipe cutting, which, if not cleaned, will cause waste chip accumulation, obstruction, and reduced cutting efficiency.

[0006] The present invention provides a pipe cutting device for power construction, comprising a worktable, an electric guide rail, and a chip extraction component;

[0007] The workbench is equipped with a fixed cover and a positioning cover, and a flexible chip-passing component is connected between the fixed cover and the positioning cover. The positioning cover is driven by an electric guide rail to move laterally and drive the flexible chip-passing component to extend and retract.

[0008] An annular guide rail is installed inside the positioning cover, and the driving end of the annular guide rail is connected to a cutting component for cutting the pipe.

[0009] The positioning cover is equipped with an air blowing device for blowing air onto the cutting assembly, and the chip extraction device is located at one end of the workbench and connected to the bottom of the fixed cover for chip extraction.

[0010] The workbench has a cavity, and the top of the workbench has a sliding opening that communicates with the cavity. The bottom of the flexible chip-passing component is equipped with an elastic component that extends into the cavity and slides with the sliding opening. The cavity is equipped with a convex plate that can move up and down and cooperates with the elastic component.

[0011] As a further optimization of the present invention, the cutting assembly includes a linear guide rail, a semi-circular frosted cover, a motor, a cutter head, and a scanning component. The driving end of the annular guide rail is equipped with a linear guide rail, and the driving end of the linear guide rail is equipped with a support plate via a connecting rod. A semi-circular frosted cover is fixed to the side of the support plate near the linear guide rail, and a movable cavity is formed inside the semi-circular frosted cover. A motor is installed on the outside of the support plate, and the output end of the motor is connected to the cutter head, with half of the cutter head extending into the movable cavity and the other half exposed outside. The scanning component is installed at the driving end of the linear guide rail and is used for scanning the cut of the pipe.

The air pump is installed on the outside of the loading block, and its blowing end extends into the loading cavity to blow air onto the surface of the scanning camera.

[0013] As a further optimization of the present invention, the air blowing component includes an annular tube and an ion fan. The annular tube is installed on the inner wall of the end of the positioning cover away from the fixed cover. A plurality of annularly arranged air blowing nozzles are connected to the side of the annular tube near the annular guide rail. The ion fan is installed on the top of the positioning cover. The air outlet end of the ion fan is connected to a duct, and the duct is connected to the annular tube.

[0014] As a further optimization of the present invention, the flexible chip-passing component includes multiple flexible covers and rings. Each flexible cover is connected to an adjacent ring. One end of the flexible cover is connected to a fixed cover and communicates with the inside of the fixed cover. The other end of the flexible cover is connected to a positioning cover and communicates with the inside of the positioning cover. The fixed cover has an inlet at the end away from the flexible cover, and the positioning cover has an outlet at the end away from the flexible cover.

[0015] As a further optimization of the present invention, the elastic element includes a T-shaped slider, a vertical rod, a force-bearing block, a spring, and a ball bearing. Multiple T-shaped sliders are slidably fitted onto the sliding opening. The multiple T-shaped sliders are located below multiple ring bodies respectively. Vertical rods extending into the cavity are slidably connected to each of the multiple T-shaped sliders. Multiple vertical rods are respectively connected to the bottom of multiple ring bodies. A force-bearing block is fixed to the bottom of the vertical rod. A spring is sleeved on the vertical rod, and the two ends of the spring are respectively connected to the T-shaped slider and the force-bearing block. A ball bearing is rolledly installed at the bottom of the force-bearing block.

[0016] As a further optimization of the present invention, the convex plate includes a second cylinder, a strip plate and a protrusion. The second cylinder is installed on the bottom wall inside the cavity. The driving end of the second cylinder is connected to the strip plate located below multiple force blocks. Multiple arc-shaped protrusions are fixed on the top surface of the strip plate at intervals.

[0017] As a further optimization of the present invention, the chip extraction component includes a chip extraction pump and a chip extraction pipe. The chip extraction pump is disposed at one end of the workbench, and the chip extraction end of the chip extraction pump is connected to the chip extraction pipe, which is connected to the bottom of the fixed cover for chip extraction inside the fixed cover.

[0018] As a further optimization of the present invention, the inner walls of both sides of the fixing cover are fixed with first shafts arranged laterally, and the adjacent ends of the two first shafts are rotatably mounted with first guide wheels for guiding the pipe. The two sides of the fixing cover are each equipped with a first cylinder, and the driving ends of the two first cylinders are connected to clamping blocks located inside the fixing cover. The adjacent sides of the two clamping blocks are each formed with an arc-shaped opening. The inner walls of both sides of the positioning cover are fixed with second shafts, and the adjacent ends of the two second shafts are rotatably connected to second guide wheels for guiding the pipe.

[0019] As a further optimization of the present invention, the number of electric guide rails is two, both of which are installed on the top of the worktable, and the sliding opening is located between the two electric guide rails. The positioning cover is installed on the drive end of the two electric guide rails.

[0020] The above-described technical solution of the present invention has the following beneficial technical effects:

[0021] 1. This invention uses an electric guide rail to drive the positioning cover closer to or further away from the fixed cover, causing the flexible chip conveying component to extend and retract, adapting to pipes of different lengths. After the pipe passes through the fixed cover, the flexible chip conveying component, and the positioning cover, it is clamped and fixed by the clamping blocks driven by the first cylinders on both sides of the fixed cover. The annular guide rail inside the positioning cover drives the cutting component to cut the pipe in annular shape. After cutting a section, the electric guide rail drives the positioning cover closer to the fixed cover, and the flexible chip conveying component adaptively retracts. The cutting component moves to the next cutting position. During cutting, the air blowing component inside the positioning cover blows air to the cutting position, causing the waste chips to enter the fixed cover along the flexible chip conveying component. Then, the chip extraction component removes the waste chips. The above design can flexibly adapt to the cutting of pipes of different lengths, effectively avoiding the accumulation of waste chips, eliminating the obstruction of the cutting operation by waste chips, ensuring the smooth progress of the cutting process, and reducing the risk of equipment failure due to waste chip problems.

[0022] 2. When the cutting assembly of the present invention cuts the pipe, the motor drives the cutter head to rotate, and the linear guide rail drives the cutter head on the support plate to move closer to the pipe for cutting. During cutting, the annular guide rail drives the linear guide rail to make the cutter head perform annular cutting action along the pipe. After cutting, the linear guide rail drives the support plate to move the semi-circular frosted cover covering the cutter head to fit against the edge of the pipe cut. Then, the annular guide rail drives the linear guide rail to move the semi-circular frosted cover along the pipe cut in annular motion. The semi-circular frosted cover can polish the pipe cut area, which can effectively remove the burrs and make the cut surface smoother and flatter, improve the processing quality of the pipe, and reduce the problems caused by uneven cuts in subsequent processes.

[0023] 3. After the pipe is cut, in order to facilitate the staff to judge whether the cut part of the pipe is ground flat, the present invention installs a scanning component on the drive end of the linear guide. The scanning component on the linear guide can be driven by the annular guide to move in a circle along the pipe cut. The scanning component can scan the annular cut part to detect whether the cut surface is flat. The cutting component of the present invention integrates cutting, grinding and scanning into one design, which reduces the error and workload of manual inspection, improves the inspection efficiency and accuracy, and enables the staff to quickly and accurately obtain the cut quality information, which facilitates the timely detection and handling of unqualified products.

[0024] 4. After the pipe is cut, the two clamping blocks can be driven away from each other by the two first cylinders to release the restriction on the pipe and remove it. However, some debris will be attached to the flexible chip conveyor. To facilitate cleaning, the present invention assembles a convex plate in the worktable. When the pipe is removed, the convex plate moves upward and abuts against the elastic element at the bottom of the flexible chip conveyor. The electric guide rail drives the positioning cover to extend and retract the flexible chip conveyor. The elastic element moves and deforms on the convex plate, causing the flexible chip conveyor to shake and shake off the debris on the inner wall. At the same time, the air blowing component blows air inward, and the debris enters the fixed cover. The chip extraction component extracts the debris. In addition, a second shaking method can be used. The electric guide rail drives the positioning cover to unfold the flexible chip conveyor. The convex plate moves up and down, and the elastic element pushes the flexible chip conveyor to shake up and down as a whole, further cleaning the debris and dust. The above design effectively solves the problem of cleaning the flexible chip conveyor, avoids equipment failure and processing quality degradation caused by debris accumulation, and extends the service life of the flexible chip conveyor.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0040] like Figure 1-13 As shown, the present invention proposes a pipe cutting device for power construction, which includes a workbench 1, an electric guide rail 101 and a chip extraction component 9.

[0041] A fixed cover 2 and a positioning cover 3 are installed on the workbench 1, and a flexible chip-passing component 4 is connected between the fixed cover 2 and the positioning cover 3. The positioning cover 3 is driven to move laterally by the electric guide rail 101 and drives the flexible chip-passing component 4 to extend and retract.

[0042] An annular guide rail 31 is installed inside the positioning cover 3, and the driving end of the annular guide rail 31 is connected to a cutting assembly 5 for cutting pipes.

[0043] An air blowing component 6 for blowing air onto the cutting component 5 is installed inside the positioning cover 3, and a chip extraction component 9 is set at one end of the workbench 1 and connected to the bottom of the fixed cover 2 for chip extraction inside.

[0044] The workbench 1 has a cavity, and the top of the workbench 1 has a sliding opening 102 that communicates with the cavity. The bottom of the flexible chip-passing component 4 is equipped with an elastic component 7 that extends into the cavity and slides in cooperation with the sliding opening 102. The cavity is equipped with a protruding plate component 8 that can move up and down and cooperates with the elastic component 7.

[0045] During operation, the electric guide rail 101 drives the positioning cover 3 to move laterally, causing the flexible chip-passing component 4 to extend and retract synchronously, thus adapting to power pipes of different lengths. After the pipe passes through the fixed cover 2, the flexible chip-passing component 4, and the positioning cover 3, the annular guide rail 31 inside the positioning cover 3 drives the cutting assembly 5 to move annularly along the pipe to complete the cutting. During the cutting process, the air blowing component 6 blows air onto the cutting area, blowing the generated chips into the flexible chip-passing component 4. The chips fall along the flexible chip-passing component 4 into the fixed cover 2, and are then removed by the chip extraction component 9 through the fixed cover 2. The bottom of the fixed cover 2 is pulled out and discharged. At the same time, the convex plate 8 in the cavity of the worktable 1 can move up and down, and cooperate with the elastic element 7 at the bottom of the flexible chip-passing part 4 that extends into the cavity. When the flexible chip-passing part 4 extends and retracts, the deformation of the elastic element 7 causes it to shake, which helps to clean the waste chips attached to the inner wall. The above can realize flexible adaptation of pipes of different lengths, without the need to frequently adjust the position of the pipes and re-fix them, which greatly improves the cutting efficiency. The waste chips are guided by air and discharged in time by the chip extraction part 9, avoiding the accumulation of waste chips that scratch the surface of the pipes and hinder the cutting operation.

[0046] In this embodiment, the cutting assembly 5 includes a linear guide rail 51, a semi-circular frosted cover 52, a motor 53, a cutter head 54, and a scanning element 55. The linear guide rail 51 is mounted on the driving end of the annular guide rail 31. A support plate 512 is mounted on the driving end of the linear guide rail 51 via a connecting rod 511. A semi-circular frosted cover 52 is fixed to the side of the support plate 512 near the linear guide rail 51, and a movable cavity is formed inside the semi-circular frosted cover 52. A motor 53 is mounted on the outer side of the support plate 512. The output end of the motor 53 is connected to the cutter head 54, with one half of the cutter head 54 extending into the movable cavity and the other half exposed. The scanning element 55 is mounted on the driving end of the linear guide rail 51 and is used for scanning the cut of the pipe. When the cutting assembly 5 is working, the annular guide rail 31 drives the linear guide rail 51 to move in a ring around the pipe. The linear guide rail 51 drives the support plate 512 to move the motor 53 and the cutter head 54 closer to the pipe. The cutting disc 54 rotates to achieve cutting. During the cutting process, the semi-circular frosted cover 52 moves with the support plate 512. Its movable cavity covers half of the area of ​​the cutting disc 54, which can initially block the splashing of waste chips. After the cutting is completed, the linear guide rail 51 drives the support plate 512 to move the semi-circular frosted cover 52 to fit the pipe cut. During this process, the position of the pipe can be adjusted as needed to fit it. The annular guide rail 31 drives the linear guide rail 51 to move in annular motion again. The cut is polished by the semi-circular frosted cover 52. At the same time, the scanning component 55 moves with the linear guide rail 51 to fully scan the cut of the pipe. The above realizes the integrated design of cutting and polishing, without the need for additional equipment replacement, effectively removes burrs from the cut, improves the pipe processing quality, and the scanning component 55 can detect the flatness of the cut in real time, reducing the error and workload of manual inspection, ensuring cutting accuracy, and improving the detection efficiency of unqualified products.

[0047] In this embodiment, the scanning component 55 includes a loading block 551, a scanning camera 552, and an air pump 553. The loading block 551 is installed on the drive end of the linear guide rail 51, and a loading cavity is formed inside the loading block 551. The scanning camera 552 is installed in the loading cavity for scanning the cut end of the pipe. The air pump 553 is installed on the outside of the loading block 551, and its blowing end extends into the loading cavity to blow air onto the surface of the scanning camera 552. After cutting and grinding are completed, the linear guide rail 51 can be driven by the annular guide rail 31 to drive the scanning component 55 to move in annularly along the pipe. The loading block 551 moves with the drive end of the linear guide rail 51, and the scanning camera 552 inside it performs annular scanning on the cut end of the pipe to capture the flatness data of the cut surface. Since waste chips easily adhere to the surface of the scanning camera 552 during the cutting process and affect the scanning accuracy, the air pump 553 on the outside of the loading block 551 continuously blows air into the loading cavity through the blowing end to clean the dust and waste chips on the surface of the scanning camera 552 in a timely manner.

[0048] It should be noted that the scanning camera 552 is connected to an external control system, which can help staff understand the scanning data in real time.

[0049] In this embodiment, the air blowing component 6 includes an annular pipe 61 and an ion blower 62. The annular pipe 61 is installed on the inner wall of the end of the positioning cover 3 away from the fixed cover 2. A plurality of annularly arranged air blowing nozzles 611 are connected to the side of the annular pipe 61 near the annular guide rail 31. The ion blower 62 is installed on the top of the positioning cover 3. The air outlet of the ion blower 62 is connected to a conduit 621, and the conduit 621 is connected to the annular pipe 61. After the cutting operation begins, the ion blower 62 on the top of the positioning cover 3 is started. The airflow generated is transported to the annular pipe 61 through the conduit 621. The annular pipe 61 blows air evenly to the cutting part of the cutting component 5 through the plurality of annularly arranged air blowing nozzles 611. The airflow can not only blow the waste generated by cutting into the interior of the flexible chip passing component 4, but also neutralize the static electricity on the surface of the pipe and equipment through the ion wind generated by the ion blower 62, reducing the adsorption of waste. The above design avoids the accumulation of waste in the cutting area. The anti-static function of the ion wind further reduces the adhesion of waste to the pipe and equipment, ensuring a smooth cutting process and improving the cleanliness of the pipe surface.

[0050] In this embodiment, the flexible chip conveying component 4 includes multiple flexible covers 41 and rings 42. Each flexible cover 41 is connected to an adjacent ring 42. One end of the flexible cover 41 is connected to the fixed cover 2 and communicates with the interior of the fixed cover 2. The other end of the flexible cover 41 is connected to the positioning cover 3 and communicates with the interior of the positioning cover 3. The fixed cover 2 has an inlet at the end away from the flexible cover 41, and the positioning cover 3 has an outlet at the end away from the flexible cover 41. When the electric guide rail 101 drives the positioning cover 3 to move, the adjacent flexible covers 41 are extended and folded through the rings 42 to adapt to the change in distance between the positioning cover 3 and the fixed cover 2. The tube enters from the inlet of the fixed cover 2, passes through the interior of the flexible chip conveying component 4, and exits from the outlet of the positioning cover 3. The two ends of the flexible chip conveying component 4 are connected to the fixed cover 2 and the positioning cover 3 respectively, forming a closed chip conveying channel. The closed channel design ensures that the chip will not leak out, and the centralized guide fixed cover 2 facilitates the chip extraction component 9 to extract the chip, thereby improving the chip processing efficiency.

[0051] In this embodiment, the elastic element 7 includes a T-shaped slider 71, a vertical rod 72, a force-bearing block 73, a spring 74, and a ball bearing 75. Multiple T-shaped sliders 71 are slidably fitted onto the sliding opening 102. These T-shaped sliders 71 are located below multiple ring bodies 42. Each T-shaped slider 71 has a vertical rod 72 slidably inserted into its cavity. The vertical rods 72 are connected to the bottom of the multiple ring bodies 42. A force-bearing block 73 is fixed to the bottom end of each vertical rod 72. A spring 74 is sleeved on each vertical rod 72, and both ends of the spring 74 are respectively engaged with the T-shaped slider. Block 71 and force-bearing block 73 are connected. A ball bearing 75 is rolled on the bottom of force-bearing block 73. When the convex plate 8 moves up and contacts the ball bearing 75 at the bottom of force-bearing block 73, the positioning cover 3 can be driven by the electric guide rail 101 to extend and retract the flexible chip-passing part 4. The upright 72 at the bottom of the flexible chip-passing part 4 drives the force-bearing block 73 to move accordingly. The ball bearing 75 at the bottom of force-bearing block 73 rolls on the surface of the convex plate 8. The force-bearing block 73 is compressed and deformed by the spring 74, which drives the upright 72 to move up and down, thereby driving the ring 42 to make the flexible cover 41 vibrate.

[0052] In this embodiment, the convex plate 8 includes a second cylinder 81, a strip 82, and protrusions 83. The second cylinder 81 is installed on the bottom wall inside the cavity. The driving end of the second cylinder 81 is connected to the strip 82 located below multiple force blocks 73. Multiple spaced arc-shaped protrusions 83 are fixed on the top surface of the strip 82. When it is necessary to clean the waste on the inner wall of the flexible chip removal component 4, the second cylinder 81 inside the cavity of the worktable 1 is activated, driving the strip 82 to move up and down. The multiple arc-shaped protrusions 83 on the top surface of the strip 82 contact the bottom of the ball bearings 75 at the bottom of the force block 73. When the electric guide rail 101 drives the positioning cover 3 to move... When the flexible chip-passing component 4 extends or retracts, the elastic component 7 moves accordingly. The ball bearing 75 at the bottom of the force block 73 moves on the surface of the strip plate 82. When the ball bearing 75 passes the protrusion 83, the spring 74 can extend or retract under the reaction force of the protrusion 83. The upright rod 72 drives the ring body 42 in the flexible chip-passing component 4 to shake. The flexible cover 41 connected to the ring body 42 shakes accordingly to shake off the waste chips in the flexible cover 41. In addition, the up and down movement of the strip plate 82 can directly drive the elastic component 7 to move up and down as a whole, realizing the overall shaking of the flexible chip-passing component 4. The aforementioned protruding plate 8 can realize two shaking methods for the flexible chip-passing component 4.

[0053] In this embodiment, the chip extraction component 9 includes a chip extraction pump 91 and a chip extraction pipe 92. The chip extraction pump 91 is disposed at one end of the workbench 1. The chip extraction end of the chip extraction pump 91 is connected to the chip extraction pipe 92, and the chip extraction pipe 92 is connected to the bottom of the fixed cover 2 for chip extraction inside the fixed cover 2.

[0054] During the cutting operation, the chip extraction pump 91 at one end of the workbench 1 is continuously started. It is connected to the bottom of the fixed cover 2 through the chip extraction pipe 92, forming a negative pressure environment inside the fixed cover 2. The waste chips in the flexible chip passing part 4 are guided into the fixed cover 2 by the air blowing part 6, and then sucked into the chip extraction pipe 92 by the negative pressure. Finally, they are discharged and collected by the chip extraction pump 91.

[0055] It should be noted that in actual use, the chip discharge end of the chip pump 91 can be connected to a waste chip collection device.

[0056] In this embodiment, first shafts 23 arranged laterally are fixed to the inner walls of both sides of the fixing cover 2. First guide wheels 231 for guiding pipes are rotatably mounted on adjacent ends of the two first shafts 23. First cylinders 21 are mounted on both sides of the fixing cover 2. Clamping blocks 22 located inside the fixing cover 2 are connected to the driving ends of the two first cylinders 21. An arc-shaped opening is formed on an adjacent side of each of the two clamping blocks 22. Second shafts 32 are fixed to the inner walls of both sides of the positioning cover 3. Useful guide wheels 231 are rotatably connected to adjacent ends of the two second shafts 32. The second guide wheel 321 guides the pipe; when the pipe is placed into the device, it can move on the first guide wheel 231 to guide the pipe, so that the pipe can pass smoothly through the fixed cover 2 and the flexible chip passing part 4. The second guide wheel 321 in the positioning cover 3 can discharge the pipe and assist in the positioning of the pipe, ensuring that the pipe remains stable during cutting. After the pipe is positioned, the first cylinders 21 on both sides of the fixed cover 2 drive the clamping block 22 to move towards the middle. The arc-shaped opening on the adjacent side of the clamping block 22 fits against the surface of the pipe to achieve a firm clamping of the pipe.

[0057] It should be further noted that in actual use, an electric push rod can be installed on the top of the positioning cover 3. When the pipe is being cut, the electric push rod applies pressure to the pipe to fix it in place and prevent the pipe from shifting during the cutting process.

[0058] In this embodiment, there are two electric guide rails 101, both of which are installed on the top of the workbench 1, and the slide 102 is located between the two electric guide rails 101. The positioning cover 3 is installed on the driving end of the two electric guide rails 101. The design of the electric guide rails 101 enables the lateral movement of the positioning cover 3.

[0059] The specific working principle of this invention is as follows:

[0060] The staff put the power pipe into the inlet of the fixed cover 2. Under the guidance of the first guide wheel 231 in the fixed cover 2 and the second guide wheel 321 in the positioning cover 3, the pipe passes through the flexible chip-passing part 4 and exits from the outlet of the positioning cover 3. The first cylinder 21 on both sides of the fixed cover 2 is activated to drive the two clamping blocks 22 to move closer to each other to clamp the pipe and complete the positioning.

[0061] According to the pipe cutting length requirements, start the electric guide rail 101 to drive the positioning cover 3 to move laterally. The positioning cover 3 drives the flexible chip passing part 4, which is composed of a flexible cover 41 and a ring 42, to extend and retract, and adjust to a suitable cutting distance. At this time, the elastic part 7 at the bottom of the flexible chip passing part 4 slides synchronously along the slide 102 of the worktable 1 through the T-shaped slider 71.

[0062] The annular guide rail 31 and cutting assembly 5 inside the positioning cover 3 are started. The annular guide rail 31 drives the linear guide rail 51 to move around the pipe in an annular shape. The linear guide rail 51 drives the motor 53 and the cutter head 54 to approach the pipe and rotate to cut through the support plate 512. At the same time, the ion fan 62 at the top of the positioning cover 3 is started and airflow is delivered to the annular tube 61 through the conduit 621. The air nozzle 611 of the annular tube 61 blows air evenly to the cutting part, blowing the waste into the interior of the flexible chip conveyor 4. The waste enters the fixed cover 2 along the flexible chip conveyor 4 and is then extracted and discharged by the chip pump 91 at one end of the workbench 1 through the chip extraction pipe 92.

[0063] After the cutting is completed, the linear guide rail 51 drives the support plate 512 to move the semi-circular frosted cover 52 to fit the pipe cut. The annular guide rail 31 drives the linear guide rail 51 to move in annular motion again. The semi-circular frosted cover 52 polishes the cut to remove burrs. Then, the scanning component 55 at the drive end of the linear guide rail 51 is started. The scanning camera 552 in the loading block 551 performs annular scanning of the cut. The air pump 553 blows air into the loading cavity to clean the surface of the scanning camera 552 to ensure scanning accuracy.

[0064] After the grinding and inspection are completed, the first cylinder 21 drives the clamping block 22 to release the pipe. The staff takes out the pipe and starts the second cylinder 81 in the cavity of the workbench 1 to drive the strip 82 to move up and down. The protrusion 83 of the strip 82 contacts the force block 73 of the elastic element 7. Through the deformation of the spring 74 and the rolling of the ball 75, the flexible chip removal element 4 is shaken. At the same time, the ion fan 62 continuously blows air to blow the waste chips attached to the inner wall of the flexible chip removal element 4 into the fixed cover 2 and discharged by the chip extraction element 9, completing the cleaning.

The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
